Description

Air purification device

Technical field

The invention relates to the field of environmental protection, and in particular to an air purification device.

Background technique

Pollutants are mainly composed of two forms, one is particulate pollutants, such as dust, bacteria, mold, etc., which are large in shape and complex in molecular structure, and are composed of a plurality of different substances or components, and the size thereof is approximately It is from one micron to hundreds of micrometers. The other is a gaseous contaminant, such as a gas-like chemical substance with odor and volatile organic chemicals. Its chemical structure is simple, composed of many chemical elements and very small, only Amy to Nano the size of.

When dust or large-sized particles are treated, electrostatic dust removal or dust removal using a high-performance dust filter is generally used. Its dust removal effect can often reach 80% or even 99.9%. However, it is not so easy to deal with volatile organic chemicals that are only ami to nanometer in length.

Typically in this type of device, two major forms of airborne pollutants (particulates and gaseous contaminants) are drawn into the system at one time. The contaminated air passes through a filter for removing particulate contaminants before entering a filter for treating gaseous contaminants for removing gaseous contaminants. Even for very high performance filters for the removal of particulate contaminants, it is not possible to remove particles in the air 100%. For air with a very high degree of pollution, such as air in a smoking place, forcing all contaminated air to pass through a filter for removing particulate pollutants and a filter for removing gaseous pollutants, the particles in the polluted air cannot Once removed in one go, residual odorous particles (such as nicotine smoky particles) accumulate on the surface of the filter used to remove gaseous contaminants, blocking the small adsorption of filters used to remove gaseous contaminants. The surface of the pores prevents subsequent gaseous contaminants from being effectively adsorbed or chemically reacted. Over time, such air purification devices can not only effectively remove odorous pollutants in the air, but also the dust accumulated on the surface of the catalyst becomes a hotbed of bacteria. The catalyst surface in the air purifier is attached with bacteria and accumulates dust. At startup, as Start the machine that releases contaminants (bacteria, taste, dust, etc.).

Moreover, the mechanisms for filtering and purifying gaseous contaminants and removing particulate contaminants are generally different. Filtering particulate pollutants is like using a sieve. The particulate pollutant filter is used to filter the particulate pollutants. The faster the wind flow rate, the more particulate pollutants can be filtered, and the effect of removing particulate pollutants is more obvious. The mechanism for purifying gaseous pollutants, whether adsorption or gasification catalytic decomposition, firstly adsorbs gaseous pollutants on the surface or material of the filter used to remove gaseous pollutants. The wind flow rate is too fast, and the pollutants are There is not enough residence time to adsorb the surface or material of the filter used to remove gaseous contaminants, and when the wind speed is too slow, the air purifying device cannot purify the gaseous contaminants in the environment in a short time.

As shown in Figure 7a, the airflow path adjuster 10 is adjusted to pass air 90 through the air cleaning device 700, and the air 90 passes through the first filter 30. That is, the airflow path adjuster 10 is adjusted to a position such that air must pass through the first filter 30. Additionally, as shown in Figure 7b, the regulated airflow path adjuster 10 can be adjusted to another position such that air must pass over the first filter 30. In both cases, air 90 will first pass the ion release tip 50.

As shown in FIG. 8, in another embodiment, the air cleaning device 800 further includes a negative ion generator including a circuit device and an ion release tip, and the ion release tip 50 is disposed at the The filter or the upstream position of the second filter 40 is removed.

As shown in FIG. 9, in another embodiment of the air cleaning device (showing the air flow path adjuster portion), a housing 15 is further included, and the switching method of the air flow path adjuster 10 is by a hinge rotation or a motor 22 The airflow path adjuster 10 is closed (as shown in Figure 9a) or opened (as shown in Figure 9b) with the airflow path adjuster 10 fixed on one side and the other side rotated. When the wind path regulator 10 is fully or partially opened, the rotating side forms an angle with the first filter 30 or the filter 30 for removing gaseous contaminants of the present embodiment, and the air 90 is forced directly Exhausted from an outlet without wind resistance.

As shown in FIG. 10, in another embodiment of the air cleaning device (showing the air flow path adjuster portion), a housing 15 is further included, and the switching method of the air flow path adjuster 10 is by a hinge rotation or a motor 22 The wind path regulator 10 is turned off (as shown in Figure 10a) or turned on (as shown in Figure 10b). At this time, the entire air flow path adjuster 10 moves forward or backward. When the air flow path adjuster 10 is fully or partially opened, it is separated from the first filter 30 or the filter 30 for removing gaseous contaminants of the present embodiment, and the air is forced to be directly discharged from the outlet without the wind resistance.

As shown in FIG. 11, in another embodiment of the air cleaning device (showing the air flow path adjuster portion), a housing 15 is further included, and the switching method of the air flow path adjuster 10 is by a hinge rotation or a motor 22 The wind path regulator is turned off (as shown in Figure 11a) or turned on (as shown in Figure 11b). At this time, the entire air flow path adjuster is pushed forward or backward, and then slipped to the side passing through the first filter 30. When the air flow path adjuster 10 is fully or partially opened (as shown in FIG. 11b), it overlaps with the first filter, and the overlapped first filter and the air flow path adjuster (22) part (1701) With greater wind resistance, air (90) is forced to exit directly from the outlet without wind resistance.

As shown in FIG. 12, in another embodiment of the air cleaning device (showing the air flow path adjuster portion), a housing 15 is further included, and the switching method of the air flow path adjuster is to rotate by a hinge or a motor to make the air flow The path adjuster is turned off (as shown in Figure 12a) or turned on (as shown in Figure 12b). At this time, the entire air flow path adjuster 12 is pushed or slid to one side of the first filter 30 when the wind flow path adjuster 20 After all or part of the opening (as shown in FIG. 12b), it overlaps with the first filter 30, and the air flow path adjuster 10 covers the windward side of the first filter 30 to further protect the first filter. It is protected from air 90 containing a high concentration of dust.

As shown in FIG. 13, in another embodiment of the air cleaning apparatus (showing the air flow path adjuster portion), a housing 15 is further included. The first filter 30 in the air cleaning device is integrated with the air flow path adjuster 30 as a whole. In the present embodiment, the filter material of the air flow path adjuster 10 can function the same as the first filter 30, that is, both for removing gaseous contaminants. The airflow path adjuster is closed (as shown in Fig. 13a) or opened (as shown in Fig. 13b), and the flow direction of the air 90 in the purifying device can be controlled. Opening the airflow path adjuster 10 can make the high dust concentration air 90 not pass. The

first filter

10, 30.

When the concentration of dust in the air is higher than the default value, the airflow path regulator will open (as shown in Figure 13b), and the air passes through the second filter (or the discharge end of the negative ion or the dust removal device), directly from the windless The outlet is discharged so that dust and particles in the air are treated first. Until the dust concentration is lower than the default value, the air flow path adjuster 10 is turned off (adjusted to a position such that air can flow simultaneously through the discharge end or the dust removal device passing through the first filter and the second filter or negative ions), Thereby treating gaseous contaminants.

14 to FIG. 16 are diagrams showing an air evolution apparatus and an operation process thereof, which can change a device which is almost impossible to perform air filtration and purification into an effective air purification device, and can be sequentially purified. Contains gaseous contaminants and particulate contaminants.

FIG. 14 shows an ordinary fanless electric fan 1400, which is not like a conventional electric fan, a dehumidifier, a dehumidifier, a cooling fan, an air conditioner, a heater, and the like, and can be caused by a fan. By adding a filter to the main air flow path, it can be converted into an air filter device. Because these airless amplifiers designed with no fan blades rely mainly on two air flow paths to achieve ventilation. (1) An air flow path is a high-pressure air (first air flow) 92 carried by a high-torque, high-pressure motor 91, as shown in the lower portion 1401 of the fanless electric fan 1400 in Fig. 14, this air flow path Flowing in the housing, if a filter 98 is added to the flow path of the air (first air flow) 92, the pressure of the air (first air flow) 92 flowing in the housing is weakened, and the low pressure air is from the Wen. Tube spray The mouth 80 is sent out, and the effect of pulling the surrounding air 97 cannot be achieved. (2) Another air flow path is a wall-attaching effect of the outer shape of the hollow circular casing 90 (as shown in the upper portion 1402 of the fanless electric fan 1400 in Fig. 14), and the surrounding air is driven (the second air flow) 97 flows through the hollow casing, and if a filter 95 is added to this air flow path, the outer shape of the hollow circular casing is changed. Thus, the Coanda effect disappears due to the change in appearance, and the surrounding air (second air flow) 97 is not pulled and flowed. These air amplifiers or fanless fan units are well designed for ventilation, but they cannot be arbitrarily matched to make them an air purification unit, making them an environmentally versatile device.

The air purifying device may also be incorporated into the air purifying method or device of the present invention by using a conventional fanless electric fan (as shown in FIG. 14) without using a fan, so that it can be matched with the filter and converted into an air. Purification device (as shown in Figure 15). Figure 15 is a side perspective view of an air cleaning apparatus of an embodiment, and Figure 16 is a partial schematic view of the air purifying apparatus shown in Figure 15. The above transformation can be achieved like this:

An air purification device 1500 includes at least one primary airflow system 100, at least one bypass airflow system 200, at least one airflow path adjuster, a first filter 2004, and a second filter 1004.

The main airflow system 100 includes at least one housing, at least one first air inlet 1001, at least one first air outlet 1002, and a first chamber 1003 between the first air inlet 1001 and the first air outlet 1002. At least one fan drives the main airflow 1008 to flow from the upstream to the downstream in the first chamber 1003, flows from the first air inlet 1001 to the first air outlet 1002, and is discharged at the first air outlet 1002. The second filter 1004 is disposed in the first chamber 1003 and flows through the second filter 1004 when the main airflow 1008 flows from the upstream to the downstream in the first chamber 1003. Contaminants in the primary airflow 1008 are purified by the second filter 1004. Wherein, the second filter 1004 is a filtering device with very low wind resistance or even no wind resistance. Further, the second filter 1004 is a negative ion generator. Further, the second filter 1004 is an electrostatic precipitator.

The side airflow system 200 includes at least one housing, at least one first filter 2004, at least one second air inlet 2001, at least one second air outlet 2002, and at least one second chamber 2003. The first filter 2004 is disposed in the housing, and the second air inlet 2001 is located in the housing The most upstream position, the second air outlet 2002 is located at the most downstream position of the casing, the first filter 2004 is located downstream of the second air inlet 2001, and the second chamber 2003 is located at the The position between a filter 2004 and the second air outlet 2002. The first filter 2004 purifies all air 2008 entering from the second inlet air 2001 of the bypass airflow system 200 and passing through the first filter 2004.

The second air outlet 2002 of the side airflow system 200 is disposed at an adjacent position of the adjacent or slightly front end (slightly upstream) of the first air outlet 1002 of the main air system 100.

The air flow path adjuster 3000 is disposed at a front or rear position of the second air outlet 2002 of the side air flow system 200, and the air flow path adjuster 3000 can be adjusted to a position so that the second air outlet 2002 becomes unobstructed. At the air outlet, the air flow path adjuster 3000 can be adjusted to another position to close the second air outlet 2002.

The airflow path adjuster 3000 can also be calibrated to different sized apertures, such that when the aperture of the airflow path adjuster 3000 is calibrated to different sizes, the air volume, wind speed of the air 2008 entering the first filter 2004 All can be adjusted accordingly.

When air (main airflow) 1008 is driven from upstream to downstream in the primary airflow system, the primary airflow enters the first chamber 1003 from the first air inlet 1001, passes through the second filter 1004, and directly It is discharged from the first air outlet 1002. The air 1008 with contaminants is subjected to primary purification as the main gas stream passes through the second filter 1004 until the concentration of the contaminants reaches a desired level, the air flow path adjuster 3000 to a position such that the second air outlet 2002 When the main airflow 1008 is discharged from the first air outlet 1002, the air is adjacent to the first air outlet 1002 or the air at the abutting position of the front end (slightly upstream), that is, The air at the position of the second air outlet 2002 is also drawn and discharged by the discharged main airflow 1008, so that the second chamber 2003 generates a negative air pressure region, and the bypass airflow 2008 flows from the second air inlet 2001. The second chamber 2003 is further purified by the first filter 2004, and the bypass airflow 2008 is drawn by the discharged main airflow 1008 when discharged from the second air outlet 2002, from the second air outlet The 2002 flows out and is discharged together with the main air flow.

In this embodiment, the electrostatic precipitator is used as the second filter 1004 and the high efficiency dust remover (HEPA, High Efficiency Particulate Air) as the first filter 2004.

The air purification system 1500 also includes a coarse dust concentration sensor, a fine dust concentration sensor, and a central processing unit. When the fan drives the main airflow 1008 from the first air inlet 1001 into the casing of the main airflow system 100, air with different sizes of particulate contaminants flows in the casing along with the main airflow 1008, passing through the first filter (static The dust collector 1004 is then ejected from the nozzle of the venturi 1002. Larger particulate contaminants are captured by the electrostatic precipitator 1004 in the housing of the primary airflow system 100, enabling first stage purification. At the same time, the other air in the environment utilizes the appearance of the hollow circular casing as a wall-attaching effect, and a large amount of surrounding air 3008 is drawn into the pipe 2009 of the hollow casing, and at the same time, the ventilation effect is achieved.

Referring to FIG. 16a to FIG. 16c together, when the air flow path adjuster 3000 is adjusted to a position that the second air outlet 2002 is closed (FIG. 16b), the air passes only through the second filter 1004 and is purified ( Since the second air outlet 2002 is closed, air does not pass through the first filter 2004, as shown in Figure 16b). After some time, the coarse dust concentration sensor senses that the coarse dust concentration in the environment has dropped to a desired level, and the central processor commands the air flow path adjuster 3000 to another position to open the second air outlet 2002 (eg, As shown in Fig. 16c, the air flow path adjuster 3000 makes the second air outlet 2002 an air outlet having no wind resistance. Since the second air outlet 2002 of the side airflow system 200 is disposed at an adjacent or slightly forward end (slightly upstream) of the first air outlet 1002 of the primary airflow system 100, the primary airflow 1008 is from the first air outlet. When the 1002 is discharged, the air adjacent to the first air outlet 1002 or the air at the abutting position of the front end (slightly upstream), that is, the air at the position of the second air outlet 2002 is also drawn by the discharged main airflow. And discharging, causing the second chamber 2003 to generate a negative air pressure region, causing the bypass airflow to flow from the second air inlet 2001 into the second chamber 2003, and the bypass airflow flows through the first filter 2004 for further air purification. . Since the bypass airflow is air that has been subjected to primary purification, the concentration of large particulate pollutants (coarse dust) is low, and therefore, the first filter 2004 is not contaminated, destroyed, or blocked, and the life of the first filter 2004 is Greatly extended.

Since the second filter (electrostatic precipitator) 1004 has a low wind resistance, the concentration of the large particulate pollutants of the air 1008 can be quickly lowered to a preset ideal level without blocking the wind flow. After that, the lower concentration of large particulate pollutants passes through the first filter 2004 with higher wind resistance, and performs comprehensive and more detailed, thorough and deeper air filtration. The size of particulate pollutants in the air can be implemented in this implementation. In the example, the air purification device having the filter "arranged in parallel with the layers in parallel with the inlet and outlet" can be filtered in a shorter time.

In other embodiments, the second filter 1004 can also be a filter for removing particulate contaminants, the first filter 2004 can also be a first filter for filters that remove gaseous contaminants.

Further, when the airflow path adjuster 3000 is adjusted to a position, that is, the second air outlet 2002 is closed, the air passes through the second filter 1004 and is purified, and the fan speed is increased to further increase the air flow rate. The second filter 1004 is more effective in removing bulky dust. When the airflow path adjuster 3000 is in another position, the second air outlet 2002 is opened, and the

air

1008, 2008 is simultaneously purified by the first and

second filters

1004, 2004, and the fan can be adjusted to another appropriate air extraction speed. The air can pass through the second filter 1004 and the first filter 2004 at the same time.

In the air purification system, the pollutants in the air are intelligently cleaned separately in order, firstly to deal with the dust and particles with a large volume, so that the concentration in the treated space is reduced to an ideal level, and finally the small micro is processed. Gas pollutants of dust or even molecular structure. The traditional one-time forced air passes through the high-performance particulate filter and the deodorizing filter, which makes it easy for the residual dust to block the taste filter, making the deodorizing filter easy to fail. Therefore, the present invention provides an air purification device that is efficient, environmentally friendly, and reduces secondary pollution.

Since the flow rate and/or flow rate of the air (side flow) entering the first filter 2004 is affected by: (1) the area of the first filter 2004 and/or (2) the influence of the diameter of the air flow path adjuster 3000, the control The area of a filter 2004 and the aperture of the airflow path adjuster 3000 can intelligently adjust the flow rate and/or flow rate of air entering the first filter 2004, allowing air (sidestream 2008) to enter the first filter at an optimal flow rate 2004. . In this embodiment, the gas pollutant concentration sensor can be used to sense the concentration of the gas pollutant in the environment, and then adjust the area of the first filter and the aperture of the air flow path regulator.

In this embodiment, there are three paths for air flow to achieve three purification methods:

One of the paths is a high-pressure, high-pressure motor that carries high-pressure air (main airflow 1008) and passes through a low-resistance second filter for primary filtration;

The second path is a wall-attached effect of the hollow circular casing, which drives the surrounding air (the second airflow 3008) to flow through the hollow casing. The air flowing through this path acts to strengthen the air in the environment. Mobility, so that the clean air in the environment is sent out as far as possible, and the polluted air at a long distance is pumped around the system as soon as possible, and the air purification system is purified;

The third path is to adjust the airflow path regulator 10 to cause the bypass airflow 2008 to enter the first filter for advanced air filtration.

In the present embodiment, an unconventional "parallel arrangement of layers in parallel with the inlet and outlet vents" is realized, so that the filter is judiciously placed in the air amplifier (ie, a fanless fan). Effectively purify the air.

The invention has more implementation methods, the position of the random adjustment device, the device filter or the air flow path regulator, as long as the position of the air flow path regulator and the extraction speed of the fan are controlled, the flow of the air in the air freshener is controlled and filtered. Current flow rate and dwell time, when the dust concentration in the air is higher than the default value, the air flow path adjuster will open (adjust to a position to allow air to pass over the first filter and only flow through the second filter ), the fan accelerates, the air passes through the dust removal device or the second filter, and is directly discharged from the outlet without the wind resistance, so that the dust and particles in the air are processed first until the dust concentration is lower than the default value, and the air flow path adjuster is Closing (adjusting to another position allows air to flow simultaneously through the first filter and the second filter or the negative ion discharge end or dust removal device) and adjusting the fan's extraction speed to pass through at least two sets of filters ( Filters for removing particulate contaminants and filters for removing gaseous contaminants) effectively remove different contaminants. Intelligent control of wind speed prevents dust from clogging filters used to remove gaseous contaminants so that filters used to remove gaseous contaminants fail.
